It could be a driver problem or a power one. To test if it's a power issue plug something else in and see if that screws up too, disconnect the DVB one first and use something other than a DVB USB tuner.

As for the possibility of it being a driver problem, I'm going to guess you've installed TBS' awful drivers. After you installed the card but BEFORE you installed the drivers was the DVB-T device okay?

If the latter is the case then it looks like the media_tree TBS uses for their drivers has a bug that's not present in your kernels version of media_tree (TBS uses old media_tree code, how old no one knows..).

The good news for you is you can use ljalves open source drivers for your TBS card, see https://github.com/ljalves/linux_media/wiki on how to install those (click the pages drop down on the right).

Thanks for advice, it can be a good track. Before install dvb-s card my dvb-t worked fine. Power maybe be the reason - dvb-s card has a socket for power supply but I didn't connect it (no free plug in my PSU, need to buy cluster). DVB-S still works fine without this power supply but maybe there is no enough power for DVB-T stick...
Apart of that is there any advantage of using open-source driver instead of the one provided by TBS?

I've tried to install open source driver according to:
https://github.com/ljalves/linux_media/wiki/Installating

but command "make" after minutes return me an error:

Could you please advise what am I doing wrong? My kernel is 4.3.
Thanks!

Thanks!

Looks like you found a bug in the code with a newer kernel, I'd post that error on ljalves issue tracker, in the meantime try a longterm kernel instead 3.18.24 maybe.

Thanks!
I need a 4.3 kernel so need to use the original drivers, however out of curiosity I will check older kernel with opensource and check how it cooperate with dvb-t tuner.
BTW - when install original driver I have to run command ./v4l/tbs-x86_64.sh to setup target architecture. It is not necessary when make opensource driver, right?

EDIT: Confirm that on 4.2 kernel and open source drivers for TBS it works fine together with DVB-T stick, no extra power needed for TBS.
